L.T.P'S Entry for the 5th anual build
Ok all, this year I will attempt a Headlight for swmbo. I stuffed up and ordered some 20700 batteries with my order from kd which finally arrived today. Hence the delay in starting. And. after all that I’m going to use 18650’s anyway.

so we have 2 xpg2 2b, 2x p60 reflector, 3 × 29mm lenses (incase I break one),2 x lg 3500 18650’s,
1 x narsil driver from lexel, 1 x usb charging board, and a momentary switch I stole from mrs dnf
and a lump of pine for the battery holder.



some quality blue prints

sorry all images down
thanks photobucket

I’m glad your parts have arrived and your show id about to get on the road. Is your pine battery holder Asbestos and what is your headband going to be?

Yeah Ben is a late entry. He lost the plot somewhere along the line.
He has been getting hassled by me daily about starting but has been waiting for his shipment from KD to arrive with parts to build something from.

ok a bit about my new addition its a rongfu45 clone which I hope to convert to cnc one day

its 3phase ran off a cheap ebay inverter which allows me to run it up to nearly double its rated speed
and down to about 10 rpm..
anyways the reason for using the 18650’s was the tested to 3400 mah comparedto the 21700 wich are rated
at 4000 not much improvement for size / weight.

a bit of machining on the pine battery holder


with switch ,driver, batts,and charging board.
now to make the covers..

Well progressing slowly ,
started with a meltdown

these were from banggood. didn’t seem to like stainless

cutting some slots

to be truthfull I am not real happy with this

so I am going tho move onto the rest of the light ,and hopefully revisit these
stainless parts before I run out of time

They got too hot and then they loose the hardeness
Better get a cut+cool spray can

Wow. Thanks for the update on the cutter. Do you have a link to it so we can stay away from them? Hows the vice?

Yep. Stainless will eat the end mills fast if you don’t keep it cool. Seen a 1” rougher go round a corner on a part and in a matter of a couple inches of feed start glowing red and disintegrate before i could stop the machine (CNC). It was on a proven part that had run several successfully already so I knew my speed/feeds were good.

Cool project, thanks for posting pics.

The trick many times with stainless is once you start a cut don’t stop. Stainless will work harden if you allow it to cool for even seconds leaving something almost like a case hardened effect on the remaining material around the cut.

If it’s available tap magic is an excellent cutting fluid.

Absolutely. The part I mentioned had to be discarded because of this even though the final dimensions were not impinged on when the tool failed. It became too hard.

Looks like dad did a few mods to it over the years. I think I have a course blade kicking around if it will work on your machine.

It is a 12” blade steve..

started machining the pocket

60 × 30 ×30mm

will need to get a collet set as the chuck isn’t rigid enough. to much protruding
below the spindle

As promised a little more progress

had to visit the lathe to recess the bezel

thought i’d run a couple of grooves across the bezel to break it up a bit

got to love the dro for drilling holes

that’s probably it till next week see how we go

Cool build mate it looks interesting.

I have used Venom cutting fluid when drilling metal its good. Its probably cheaper then the Worth its made by Sutton tools.

Its good to see you converted with the DRO. A whole new world opens up with it.
Your block looks rather hollow from what one can see from the picture in the vice.

I tried lot of different end mills from Banggood on aluminium with my CNC , i have yet to find some that are not crap, wih a european made end mill the cutting load is almost non existant and surface finish excellent the banggood ones are hard on the machine and make burrs everywhere and it’s very easy to brake them since they hardly cut, they are good on wood though for the price, better than the typical router bits with straight cutting edges.
